I'm looking for information on building a bucket for drifting. It's not that I'm to cheap to buy a drift sock, well yes it is, but if a bucket will work why spend the money. I know that you must drill holes in the bottom, but how many and what size, and I assume that you would have to take off the bail and attach a rope of some sort. I think it would take more than 1 for a 16' river john. Thanks in advance.
